So im about 5'11 and weight now 170lbs. I would like to get to about 180-190 pounds but without losing my definition. I am currently well defined and do not want to lose; however, i need to pack on some pounds. I would like to know what i can do to reach my goal i workout 3 - 4 days a week with my work schedule. I'm more interested in certain supplements or nutrition ideas. Currently i only take a probolic protein shake after workouts. Should i consume more protein also would be my next question and if so how much?
